True to Campagnolo’s reputation of engineering prowess, the Campagnolo Record 11-speed chain offers a smooth shift that lasts and minimises drivetrain friction, thanks to a reduced chain width of just 5.5 mm and the Ni-PTFE anti-friction coating. Due to the hollow pin construction, the weight of the chain has been decreased significantly, while strength has been maintained.
